▪ reheat
Preset values make it easy to use the same value in the schedule. If
you later want to change the value, you only have to do it in 1 place
(see also operation manual and/or user reference guide).
Storage comfort: Only applicable if the desired tank temperature is
NOT weather dependent. The storage comfort temperature denotes
the higher desired tank temperature, where the tank heat up cycle is
prioritized till the reheat set point. It is the desired temperature when
a storage comfort action is scheduled (preferably during night).
# Code
[7.4.3.1] [6-0A] 30~80°C (default: 60°C)
Storage eco: The storage economic temperature denotes the lower
desired tank temperature. It is the desired temperature when a
storage economic action is scheduled (preferably during day).
# Code
[7.4.3.2] [6-0B] 30~50°C (default: 45°C)
Reheat: The desired reheat tank temperature is used:
▪ in scheduled + reheat mode, as guaranteed minimum tank
temperature: if the tank temperature drops below this value, the
tank is heated up.
▪ during storage comfort, to prioritize the domestic hot water
preparation. When the tank temperature raises above this value,
domestic hot water preparation and space heating/cooling are
executed sequentially.

Weather dependent
The weather dependent installer settings define the parameters for
the weather dependent operation of the unit. When weather
dependent operation is active the desired tank temperature is
determined automatically depending on the averaged outdoor
temperature: low outdoor temperatures will result in higher desired
tank temperatures as the cold water tap is colder and vice versa. In
case of scheduled or scheduled+reheat domestic hot water
preparation, the storage comfort temperature is weather dependent
(according to the weather dependent curve), the storage economic
and reheat temperature are NOT weather dependent. In case of
reheat only domestic hot water preparation, the desired tank
temperature is weather dependent (according to the weather
dependent curve). During weather dependent operation, the end-
user cannot adjust the desired tank temperature on the user
interface.

Schedule temperatures
The possible actions of the
temperature are:
▪ Presets (default): the predefined
temperatures storage comfort, storage
economic, and storage stop. The
predefined temperature are set in the
menu structure.
▪ Custom: custom temperatures within
the allowable range and storage stop.
Note: When selecting this value, it is
NOT possible to select
dependent tank temperatures.
